                VISX ANNOUNCES NEW STOCK REPURCHASE PROGRAM
               COMPANY TO REPURCHASE UP TO 10 MILLION SHARES

         SANTA CLARA, CALIFORNIA, APRIL 4, 2001 - VISX, INCORPORATED (NYSE
Symbol: EYE) today announced that its Board of Directors has authorized a
new Stock Repurchase Program under which up to 10 million shares of the
Company's common stock may be repurchased.

         VISX has repurchased approximately 13 million shares of its stock
since 1997. In the last three months alone, VISX has repurchased over 4
million shares, or approximately 7% of the shares outstanding.

         Commenting on the repurchase plan, Liz Davila, VISX President and
Chief Executive Officer, said, "The Board's unanimous decision to adopt a
new program reflects our continued commitment to enhancing stockholder
value. VISX is both the technology and market leader in our sector. We
believe the repurchase of our stock represents a compelling investment
opportunity and is prudent use of our capital."

         Under the new plan, the Company will continue to conduct purchases
through open market transactions in accordance with applicable securities
laws. The amount of shares purchased and the timing of purchases will be
based on a number of factors, including the number of shares needed for
replenishment of employee benefit plans, the market price of the stock,
market conditions, and as the company's management deems appropriate. As a
result of these factors, the actual number of shares repurchased cannot be
precisely determined at this time.

         The foregoing statements are forward-looking statements within the
meaning of the Private Securities Litigation Reform Act of 1995. Such
statements are based on management's current expectations and actual
results could differ materially. Additional discussion of factors affecting
the Company's business is contained in the Company's most recent filings
